IMPROVEMENT IN STEAM AND WATER INJECTORS.

To all whom it may concern:

Be it known that I, SAMUEL S. JAMIsoN, Jr., of Saltsburg, in the countyof Indiana and State of Pennsylvania, have invented a new and ImprovedSteam and Water Injector 5 and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing making a part of this specification, in which-Figure l is a sectional elevation; Fig. 2, a transverse verticalsection.

This invention relates to the steam-injector used -for filling boilerswith water and it consists in a double conical piece of metal placedwithin and lengthwise of the conducting-pipe of the instrument, in frontof the steam and watersupply pipes, an annular space being left betweenthe said conical piece and its inclosingpipe for the passage of water tothe boiler, the object of the conical piece being to more thoroughlycommingle the steam and water than they would otherwise be, andconsequently to more rapidly and completely condense the steam.

Referring to the drawing, a is the double conical piece aforesaid, thesame being secured within the pipe b by means of connecting-arms c,

three, more or less, in number. The rear end of the piece ais entered bythe mouth of the watersupply pipe d. e is the steam-pipe. rIhe conicalpiece produces a rolling motion of the steam and Water toward thecenter, which operates to thoroughly commingle the two agents. Shouldersj, located between the end of the conical waterpipe d and the inside ofthe pipe b, serve to assist the steam in checking the water if reactiontakes place. The conical piece directs the Water in such cases towardthe shoulders f.

In this instrument the water takes a straight course, all the turning ofcorners being done by steam, which will do this better than water. Thedevice is also intended for raising water from Wells, llingengine-tanks, &c.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The double conical piece a, in combination with an injector, asspecified.
